We have came to the conclusion that more attention shall be paid to the research of stealthy materials.

Based on the structure design of microwave stealth material, the absorbing properties of bi-layer carbon cluster-like microwave stealthy materials with different thickness have been studied.

The design, a winner of the prestigious 2011 Red Dot Award, combines sustainable materials and stealthy aesthetic into a resting place that would even make Dracula jealous.
